Definitions

  • Coated cutting tools according to the present invention have surprisingly shown fever pores at the inner part of the coating and this is promising for a wear resistant coating aimed for metal cutting applications.
  • the new method as disclosed above have made it possible to produce an inner TiN layer and a subsequent TiCN layer on the Ni-containing substrates without intermetallic phases disturbing growth. It has proven to be possible to provide a TiN layer and a subsequent fine grained columnar TiCN layer even on substrates with a Ni in the binder.
  • the TiCN of the present invention is a layer comparable to a TiCN deposited on cemented carbide with Co binder.
  • the new layer shows improved properties relating to the formation of intermetallic phases, pores and disturbances relating to the orientation of the layer and subsequently deposited layers.
  • Technical effects can be increased flank wear resistance and/or increased flaking resistance and/or increased crater wear resistance in metal cutting operations of for example steel.
  • the metallic binder comprises 3-8 wt% Co, preferably 5-6 wt% Co.
  • Cemented carbide substrates with an alternative binder were manufactured with a binder comprising about 80.7 wt% Ni, 13.7 wt% Fe and 5.6 wt% Co.
  • the binder content in the cemented carbide was about 7 wt%.
  • the cemented carbide substrates with the alternative binder were manufactured from a powder mixture with a composition of about 6.09 wt% Ni, 1.02 wt% Fe, 0.039 wt% Co, 1.80 wt% Ti, 2.69 wt% Ta, 0.41 wt% Nb, 0.09 wt% N and balance WC.
  • the powder mixture was milled, dried, pressed and sintered at 1450°C.
